that directory.
* defs.h utils.c (error warning): Make message be const.
* main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr

* monitor.c monitor.h (monitor_get_dev_name): New function. Does

* remote-e7000.c: Remove debugify stuff. Change printf, fprintf
to _filtered forms to make output appear in GUIs. Replace all
uses of SERIAL_READCHAR with readchar, which has better error
checking.
* (e7000_parse_device): Add prototype.
(readchar): Improve doc. Handle random serial errors.
(expect): Disable notice_quit code. It's busted. Remove
serial error handling (it's now handled in readchar). Remove
remote_debug echoing. That's handled in readchar as well.
(e7000_parse_device): Remove serial_flag arg. It's not
necessary.
(e7000_open): Split into two pieces. Second part is
e7000_start_remote, and is error protected. Now, when we connect
to the target, we setup the initial frame and registers so that
the user gets an immediate indication of where the target is.
(gch): Remove debug output. That's handled by readchar.
(e7000_read_inferior_memory): Handle errors better.
(_initialize_remote_e7000): Get rid of `<xxx>' things from

fields of gdb_callback.

operations.
(gdbsim_wait, gdbsim_resume): Move call to sim_resume into

* config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
since gcc automatically includes it
Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
* procfs.c: Substantial (but incomplete) changes to support
sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
struct now has substructs like struct flt_ctl instead of
just a fltset_t and has a ctl_fd, status_fd, as_fd, and
map_fd instead of a single fd. Non-sysv4.2mp procfs models
still have the structs and multiple fds, but don't use the
entire struct and the four fds all point to the same thing.
We use PROCFS_USE_READ_WRITE to decide whether to talk to
procfs with reads/writes or use ioctl instead. We use
HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
multiple fds or not. PROC_NAME_FMT is split out into
CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
STATUS_PROC_NAME_FMT.
(procfs_notice_signals): now a necessary wrapper around
(notice_signals): which are the new guts for noticing signals
(open_proc_file): gets a new flag arg used in sysv4.2mp to
determine whether or not to attempt to open the ctl_fd.
(procfs_read_status): new local function, reads procfs status
(procfs_write_pcwstop): new local function, writes a PCWSTOP
(procfs_write_pckill): new local function, writes a PCKILL
(unconditionally_kill_inferior): remove signo since we now
just call procfs_write_pckill().
(procfs_xfer_memory): call lseek with SEEK_SET rather than 0
(proc_iterate_over_mappings): the whole function is ifdefed
on UNIXWARE to keep things readable.
Expanded the syscall_table to include new potential sysv4.2mp
members. Note that all ifdefs of UNIXWARE should be eliminated
if possible or renamed to describe what's being selected for a
bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
IRIX specific code now also checks it's not UNIXWARE.
* config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
* config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
"/debug/%d" as PROC_NAME_FMT used to be
Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
* mn10300-tdep.c: Almost completely rewritten based on mn10200
port.
* config/mn10300/tm-mn10300.h: Likewise.
Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
* config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
lousy out-of-date clone of remote.c.
Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
* remote.c: Fix problems realized while showering.
* (hexnumlen): Add prototype. Use max, not min.
* (remote_write_bytes remote_read_bytes): Fix max packet size
calculations to properly account for packet overhead. Also handle
(probably rare) case where remote_register_buf_size isn't set.
* remote.c: Fix doc for `C' and `S' commands to indicate full
address.
* (remote_ops extended_remote_ops remote_desc remote_write_size):
Make static.
* (remote_fetch_registers remote_write_bytes remote_read_bytes):
Record size of response to fetch registers command, use this to
limit size of memory read and write commands.
* (push_remote_target): New function to make it possible to have
another target switch to the remote target.
* target.h: Add prototype for push_remote_target.
* sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
for hosts which default to unsigned chars (such as SGI's).
* (_initialize_sh_tdep): Don't set remote_write_size. It's now
handled automatically in remote.c.
Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
* blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
find_pc_sect_function(), find_pc_sect_partial_function(): new
functions for debugging overlays; pc without section is ambiguous.

add section argument to check_duplicates(); check section as well
as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
breakpoint_thread_match(), bpstat_stop_status()];

use INIT_SAL() macro to zero-out new sal structures;
make resolve_sal_pc() fix up the sal's section as well as its pc;
match on section + pc in clear_command() and delete_breakpoint();
account for overlay sections in insert_breakpoints(),
remove_breakpoint() and breakpoint_re_set_one();
all this to support overlays where a PC is not unique.
* exec.c: change xfer_memory() to handle overlay sections.
* findvar.c: change read_var_value() to handle overlay sections.
* frame.h: declaration for block_for_pc_sect() [blockframe.c].
* infcmd.c: jump_command() warns against jumping into an overlay
that's not in memory. Also use INIT_SAL() to initialize sals.
* infrun.c: wait_for_inferior() sets a flag to invalidate cached
overlay state information; Also use INIT_SAL() to init sals.
* m32r-rom.c: modify load routines to use LMA instead of VMA.
* m32r-stub.c: mask exit value down to 8 bits; screen out any

instead of VMA address, for overlay sections.
Add numerous functions for finding a PC's section / overlay,
translating between VMA and LMA address ranges, determining if an
overlay section is mapped, etc. Add several user commands for
overlay debugging. Add support for a "generic" form of automatically
reading overlay mapping info from the inferior (based on the default
(simple) overlay manager which Cygnus provides as an example).
* symtab.[ch]: add functions find_pc_sect_symtab(),
find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
for lookup; modify lookup_symbol and decode_line_1() to use them;
modify find_function_start_sal() to account for overlay sections;
add macro INIT_SAL() for initializing struct symtab_and_line.
